        Features:

        • Interface Between the Proximity Probe and 3500 Monitoring System Signal Conditioning
        • Combines Capability of Eddy Current Sensing with Extended Linear Range Measurement
        • Operates in Conjunction with the 3300 XL 11 mm Extension Cable and 3500 Monitors
        The 330704-020-100-90-02-00 operates as the 3300 XL 11 mm Proximity Probe in a 3500 rack-based monitoring system, providing reliable non-contacting vibration and displacement measurements for all modules within the system. It continuously converts changes in eddy current field into a 3.94 V/mm (100 mV/mil) output signal and transmits this data through the extension cable to the 3300 XL 11 mm Proximitor Sensor for signal conditioning, supporting steady state operation of all monitors and modules. Seamless signal integrity is standard with the 330704-020-100-90-02-00, however using an optional FluidLoc cable configuration will allow enhanced protection against oil and liquid ingress through the cable interior in harsh industrial environments. The 330704-020-100-90-02-00 has made improvements in several areas over previous 7200-series probe designs in addition to incorporating the large 11 mm tip diameter for extended linear range capability within the 3500 rack.

        The 330704-020-100-90-02-00 provides essential sensing functions common to the entire transducer system, and is a critical component of the monitoring path, directly affecting the proper, normal operation of the overall monitor system. One 330704-020-100-90-02-00 probe is required per measurement channel depending on the desired monitoring point. The 330704-020-100-90-02-00 occupies only a single probe mounting position in the machine housing and is always located at the measurement target position (the dedicated sensing point for axial position, differential expansion, or rod drop applications).

        For Dual Probe Redundant Measurement applications, the 3500 System requires a second 330704-020-100-90-02-00 probe module installed in the redundant measurement position. In addition to standard single probe operation, the redundant configuration also performs automatic signal validation. The 3500 dual probe configuration executes failover using the internal comparison logic specified in the monitor configuration options. Using this method, the redundant probe system continually monitors the health of both 330704-020-100-90-02-00 probes. If the system detects that the primary 330704-020-100-90-02-00 probe is no longer providing stable output (outside configured linear range/ tolerance levels), it will automatically transfer the measurement to the secondary 330704-020-100-90-02-00 probe and place an event in the System Event List.

        The 330704-020-100-90-02-00 Bently Nevada 3300 XL 11 mm Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 330704-020-100-90-02-00 is a 3300 XL 11 mm probe with M14 x 1.5 thread and armored cable construction, featuring an unthreaded length of 20 mm, an overall case length of 100 mm, and a total cable length of 9.0 meters (29.5 feet). This 330704-020-100-90-02-00 probe is equipped with a miniature coaxial ClickLoc connector and utilizes standard cable technology, with no agency approval requirements specified.

        The 330704-020-100-90-02-00 probe serves as a core component of the complete 3300 XL 11 mm Proximity Transducer System, which includes the 3300 XL 11 mm probe, 3300 XL 11 mm extension cable, and 3300 XL 11 mm Proximitor Sensor. The system delivers a 3.94 V/mm (100 mV/mil) output for non-contacting vibration and displacement measurements on fluid film bearing machines. The 330704-020-100-90-02-00 probe features a large 11 mm tip diameter, enabling this transducer system to achieve a significantly longer linear range compared to the standard 3300 XL 8 mm Transducer System.

        This 330704-020-100-90-02-00 proximity probe is specifically designed for demanding industrial applications where extended linear measurement range is essential. The 330704-020-100-90-02-00 excels in axial (thrust) position measurements, providing critical monitoring of rotor thrust position in turbomachinery. For steam turbine applications, the 330704-020-100-90-02-00 enables precise ramp differential expansion measurements, solving the challenge of monitoring thermal growth differentials between rotor and casing during startup and shutdown cycles. In reciprocating compressor installations, the 330704-020-100-90-02-00 provides accurate rod position or rod drop measurements, preventing catastrophic failures by detecting piston rod loosening or wear. The 330704-020-100-90-02-00 also supports tachometer and zero speed measurements, ensuring reliable speed detection across the entire operational range. Additionally, the 330704-020-100-90-02-00 generates phase reference (Keyphasor) signals essential for vibration analysis and rotor balancing procedures.

        The 330704-020-100-90-02-00 probe incorporates advanced engineering features that ensure reliable operation in harsh industrial environments. The 3300 XL 11 mm Proximitor Sensor, designed to replace legacy 7200-series 11 mm and 14 mm Transducer Systems, requires complete system migration when upgrading from older installations. The 330704-020-100-90-02-00 probe features gold-plated brass ClickLoc connectors that lock securely into place, preventing connection loosening due to vibration. The patented TipLoc molding method creates a robust bond between the probe tip and probe body, while the CableLoc design provides 330 N (75 lb) pull strength for secure cable attachment. The 330704-020-100-90-02-00 comes standard with a locknut featuring pre-drilled safety wire holes for additional security. Optional FluidLoc cable technology prevents oil and liquid leakage through the cable interior, while connector protectors provide enhanced environmental protection in humid or moist conditions.
